[glow=Green, 6, 90%]Hey all,[/glow] [glow=Navy, 4, 90%]I would like to start a new forum called "Water Chemistry," or something to that effect. We all have questions from time to time concerning Ca levels and Alk levels and how the two are interrelated. I have been reading several articles on the effects of long-term build-up of chlorides in our tank -- that is another subject that is worth checking out. And how many of you know what your Magnesium levels are? Is it important to know?[/glow] [smiley=speechless.gif] [glow=Navy, 4, 90%]If you think that a forum on "Water Chemistry" would be a good idea, post a YES! in this thread. That will give us a good feel for whether the forum is needed or not.[/glow] [smiley=idea.gif] [glow=Green, 6, 900]Anyway, Thanks!!![/glow] [smiley=2thumbsup.gif] Edit: Color for clarity.
